Risk of Ectopic Pregnancy in Women With Inflammatory Bowel Disease: A 22-Year Nationwide Cohort Study.

BACKGROUND & AIMS: Few data are available on adverse events of pregnancy in women with inflammatory bowel diseases (IBD), such as ectopic pregnancy. We assessed the risk of ectopic pregnancy in pregnancies of women in Denmark with IBD compared with those without IBD over a 22-year period. We also examined the disease-specific risks of ectopic pregnancies in pregnancies of women with ulcerative colitis (UC) or Crohn's disease (CD) who underwent IBD-related surgical procedures. METHODS: We performed a retrospective study of all women of child-bearing age (ages, 15-50 y) registered in the Danish National Patient Registry with at least 1 pregnancy during the period from January 1994 through December 31, 2015. We collected data on all women with an ectopic pregnancy, hydatidiform mole, miscarriages (spontaneous and other abortions, including abnormal pregnancy products, missed abortion, and pregnancy without a fetus), induced abortions, and births in women with and without IBD. Our study population included 7548 pregnancies in women with UC, 6731 pregnancies in women with CD, and 1,832,732 pregnancies in women without IBD. We controlled for multiple covariates, including pelvic and abdominal surgery. RESULTS: Women with CD had a greater risk of ectopic pregnancy, per pregnancy, than women without IBD (odds ratio [OR], 1.23; 95% confidence interval [CI], 1.01-1.49), whereas women with UC did not (OR, 0.98; 95% CI, 0.80-1.20). In pregnancies of women with CD and UC who underwent IBD-related surgery before pregnancy, there was a nonsignificant increase in risk of ectopic pregnancy compared with pregnancies in women with IBD who did not have surgery (OR, 1.49; 95% CI, 0.91-2.44 for CD, and OR, 1.17; 95% CI, 0.54-2.52 for UC). CONCLUSIONS: We found a statistically significant increased risk of ectopic pregnancy in pregnancies of women with CD compared with pregnancies of women without IBD. Surgery for IBD before pregnancy increased the risk of ectopic pregnancy, although this increase was not statistically significant.

Sexual Health in Women with Inflammatory Bowel Disease in the Danish National Birth Cohort.

BACKGROUND AND AIMS: Previous studies indicate an increased risk of sexual dysfunction in women with inflammatory bowel disease [IBD] but none have examined sexual function in a large population-based cohort. METHODS: To investigate the risk of sexual dysfunction in women with IBD, we used data from the Danish National Birth Cohort, a nationwide study of 92 274 pregnant women recruited during 1996-2002. We performed a cross-sectional study based on mothers who participated in the Maternal Follow-up in 2013-14. The outcome was self-reported sexual health. Information regarding demographics and IBD characteristics was retrieved from the Danish National Patient Register. Using regression models and adjusting for important confounders, we compared sexual function in women with and without IBD. RESULTS: The study population consisted of 38 011 women including 196 [0.5%] with Crohn's disease [CD] and 409 [1.1%] with ulcerative colitis [UC]. Median age was 44 years. Compared to women without IBD, women with UC did not have significantly decreased sexual function, while women with CD had more difficulty achieving orgasm (adjusted odds ratio [aOR] 1.53; 95% confidence interval [CI] 1.02-2.30], increased dyspareunia [aOR 1.71; 95% CI 1.11-2.63] and deep dyspareunia [aOR 2.00; 95% CI 1.24-3.22]. The risk for difficulty achieving orgasm and deep dyspareunia was further increased within 2 years of an IBD-related contact/visit [aOR 1.81; 95% CI 1.11-2.95; and aOR 2.37; 95% CI 1.34-4.19]. CONCLUSIONS: Women with CD have significantly increased difficulty achieving orgasm and increased dyspareunia. Physicians should be cognizant of and screen for sexual dysfunction in this group of patients.

Children Born by Women With Rheumatoid Arthritis and Increased Susceptibility for Chronic Diseases: A Nationwide Cohort Study.

OBJECTIVE: Fetal exposure to maternal rheumatoid arthritis (RA) might impact the long-term risk of disease in the offspring. We examined a possible association between maternal RA and 15 selected groups of chronic diseases in the offspring. METHODS: This nationwide cohort study was based on the Danish health registries and included data on all children born alive in Denmark between January 1, 1989 and December 31, 2013. The cohort comprised 2,106 children born by women with RA (exposed), and 1,378,539 children born by women without RA (unexposed). Cox proportional hazards regression models were used, taking a large range of confounders into consideration, and the hazard ratios (HRs) of child and adolescent diseases were calculated. RESULTS: In children exposed to maternal RA in utero, the HR of thyroid diseases was 2.19 (95% confidence interval [95% CI] 1.14-4.21), epilepsy 1.61 (95% CI 1.16-2.25), and RA 2.89 (95% CI 2.06-4.05). The HRs for anxiety and personality disorders and chronic lung disease including asthma were in the range of 1.15-1.16, but these were not statistically significant associations. CONCLUSION: Our results suggest that in utero exposure to maternal RA is associated with an increased risk of thyroid disease and epilepsy in childhood and adolescence, and in particular an increased risk of RA, compared to children born to mothers without RA. These important findings should encourage pediatricians and general practitioners to have an increased awareness of certain chronic diseases in children exposed to RA in utero.

The Association Between Maternal Chronic Inflammatory Bowel Disease and Long-term Health Outcomes in Children-A Nationwide Cohort Study.

BACKGROUND: Very little is known about the long-term impact of maternal inflammatory bowel disease (IBD) on the offspring's future health. We aimed to examine whether children born to mothers with IBD had an increased risk of long-term morbidities. METHODS: In this nationwide register-based cohort study, including all children born alive in Denmark between 1989 and 2013, we investigated the association between maternal IBD and 15 selected disease categories of physical and mental conditions in the offspring. We used multivariate regression models estimating the hazard ratio (HR) of long-term child morbidities. RESULTS: The cohort comprised 9238 children born to women with IBD (exposed), and 1,371,407 born to women without IBD (unexposed). Median follow-up time among the exposed was 9.7 years (interquartile range [IQR] 4.9-15.7) and 13.8 (interquartile range 7.4-19.9) among the unexposed. In children, who in utero had been exposed to maternal ulcerative colitis, the HR of IBD in the offspring was 4.63 (95% confidence interval, 3.49-6.16). For maternal Crohn's disease, the HR of IBD in the offspring was 7.70 (95% confidence interval, 5.66-10.47). For all other diseases in the offspring, we did not find a significantly increased risk associated with maternal IBD. CONCLUSIONS: Children born to mothers with IBD are more likely to be diagnosed with IBD themselves, compared with children born to women without IBD. Our data otherwise do not provide evidence for an increased risk of any of the other examined diseases in the offspring.

Treatment of the Pregnant Patient with Inflammatory Bowel Disease.

Research regarding fertility, medication safety, and pregnancy outcomes is increasing, but there are still many knowledge gaps in these areas. Women with ulcerative colitis and Crohn's disease may have decreased fertility because of voluntary childlessness and inflammatory bowel disease (IBD) surgery, and women with Crohn's disease may also have decreased ovarian reserve. Initial studies show that in vitro fertilization is a viable option, and laparoscopic ileoanal pouch anastomosis surgery improves fertility rates. Additional research is needed on the effect of disease activity on fertility and on the rates of pregnancy loss and ectopic pregnancies. We do not know how to reliably measure disease activity during pregnancy or the effect of pregnancy on the microbiome. Although immunomodulators and anti-tumor necrosis factor medications are relatively safe during pregnancy, the long-term effects of these medications on the child are unknown. The recommended mode of delivery is still debated, especially for women after ileoanal pouch anastomosis. There are multiple studies on the relative safety of immunomodulators and anti-tumor necrosis factor medications during pregnancy, and we know how to safely treat a pregnant patient with a disease flare. The best way to manage women with IBD who are pregnant or contemplating pregnancy is a multidisciplinary approach. Team members often include a gastroenterologist, a high-risk obstetrician, an infertility specialist, a colorectal surgeon, and a pediatrician with experience in caring for children of mothers with IBD. By integrating expertise from these disciplines, women with even very complex IBD should be able to have a healthy pregnancy and delivery.
